-IMPRCWEMENT IN RAILWAY-GATES.

Specification forming part of Letters Patent No. 15114741, dated May 5,1874; application filed February 23, 1874.

To all whom it may concern:

Be it known that I, JULIUs KE'IsTER, of Macon county, Illinois, haveinvented a Railway-Gate, of which the following is a specification:

My invention relates to an improvement in .railway-gates, designed chieyto take the place of cattle-guards. Its construction and operation canbe better understood by reference to the accompanying drawing.

Figure l shows a broken section of my invention in perspective. Fig. 2is an elevation of my invention on a vertical section of track. Fig. 3is an elevation of a section of railwaytrack together with my invention.

A and B are rotating shafts, having their bearings in the permanently-attached supports E E', and connected by chains F F. c and c arepawls attached to rails G C. b b are wheels having a ratchet orprojection on one side, and are permanently attached to the shaft B. Dis a guide for the rail C, showing' the spring cl in the broken section.t t are uprights of the gate. a and a are weights to bring the gate inposition. The rail G is hinged or pivoted to the block c, which, in itsturn, is attached to the Inain rail.

The gate is operated by the outside of the car-wheel pressing the rail Cdown, bringing the pawl c against 4the projection of the wheel b,forcing it around, thereby turning the shaft B, and indirectly, by meansof chain F, the shaft A, bringing the uprights t t t toward the trackand from the train. As the train strikes the rail C somel time beforeC', it turns the shaft B sufficient to get the projection on the wheel bout of the way bythe time C comes down. The operation is reversed by atrain from an opposite direction. In this case the rail G' is firstoperated on, and pawl c misses the projection of wheel b.

The rail C, pawl c, ratchet b, support E, guide or guides D, spring d,and chain Fare arranged reversely on the opposite sides of the track, sothat the down-train operates on one side and the up-train on the otherside of the track, always turning the gate in the direction the train isgoing.

The rails G C are made long enough to reach from one set of wheels toanother, and the pawls are guided by a bolt working in a slot, as shownin the drawing.

I claim as my inventionl. The combination of they rail C, spring d,guide D, and pawl c, as and for the purpose set forth.

2. The combination of the shafts A and B, supports E E', ratchet-wheelb, and chains F F', as and for the purpose set forth.

3. The combination, in a railway-gate, of shafts A B, rail C, pawl c,wheel b, support E, chain F, guide D, spring d, and uprights t t t, asand for the purpose set forth.
